Charged in the shooting incident is Mohammed Laghaoui, 19. He faces single counts of attempted aggravated murder and attempted murder and two counts of felonious assault, police said. He is scheduled to appear in court on Monday.

The incident spurred fear and disruption in the neighborhood, where residents of the Orchard of Landen apartments were greeted at about 10 p.m. by gunfire, sirens and chaos.

The troubles had begun about two hours earlier, when Barnes was called to the apartment complex to investigate the report of a domestic dispute. Laghaoui’s brother and father, whose names have not been released, told police he had threatened to kill them, police said.

The deputy spoke to them for about 40 minutes. Ultimately, they decided not to press charges. Barnes left.

Less than an hour later, Laghaoui punched his dad in the face, police said. Barnes returned.

She didn’t park in the open because she didn’t want to be seen. But as the suspect came down the stairs, there was nowhere to hide.

This was the first time Barnes has fired her weapon in seven years with the sheriff's department.

We're sorry, but something went wrong

Barnes, a Mason High School graduate and soccer star in college, climbed over a wall and radioed for help. Another deputy, hearing gunfire, pulled into the apartment complex and helped Barnes to safety. Soon, she would be on her way to the hospital for treatment.

"We feel pretty confident that she is going to recover from that and be able to come back and do what she does," Sims said.

The suspect went back upstairs to the apartment this started in. His family members shut the door in his face. Police say he fired into the door, striking his father in the hand. Sims said the wound might require surgery but was not life-threatening.

The father tried chasing his son, police said, but could not catch him.

Authorities couldn’t either. There was now a man armed with a rifle in the area.

Authorities stopped letting people into the apartments and asked residents in and around Deerfield Township to stay where they were. An alert pinged across thousands of phones in the area. A helicopter flew overhead while police set up a perimeter.

Emily Johnson, of Maineville, would be stranded in the parking lot of a Meijer grocery store for about seven hours.

"It's crazy. This kind of thing doesn't happen around here. You never think it's going to happen to you," the 17-year-old said. "I'm just glad we get to go home."

Brian Freedman, a 28-year-old resident of the Orchard of Landen apartment complex, got home just before police shut down everything around it.

He had gone to see a movie and was welcomed at home by police carrying shotguns and wearing bulletproof vests.

"I don’t know if I've ever seen so many police officers in one place," Freedman said.

Officials throughout the region, including some from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, aided in the search.

Active shooter in the area behind Kroger in Landen. Be advised to stay inside and not open doors to strangers.

The manhunt lasted until 4:30 a.m. Friday, when authorities said the suspect tried to return to his father and brother. Police arrested him at the apartment without incident. Sheriff Sims called it an “uneventful" arrest.

Not much is known about Laghaoui.

Kevin Waldmann, a person who used to be close friends with him, said the Laghaoui he knew was never mean to anyone. Waldmann got to know Laghaoui through their love of skateboarding. He said Laghaoui let him borrow his skateboard for a week before he could get his own.

"That's the crazy thing. He was one of the nicest kids I ever met," Waldmann said.

Laghaoui attended Lakota East High School and was an honor-roll student his freshman year, according to newspaper archives. At some point during high school, Waldmann said he stopped seeing his friend and learned he was taking online classes to earn his diploma.

The last time Waldmann saw Laghaoui, about a year ago, the 19-year-old was working at Subway. He seemed all right.

"I don't know the whole story," said Waldmann. "I feel bad for him for whatever is going on for him, but I feel a lot worse for the officer who was shot."

Laghaoui did not have a criminal record, the sheriff said. Investigators are still trying to pin down a motive.

The Enquirer has requested 911 calls and other documents related to the shooting, which could help shed more light on exactly what happened – and why it happened. As of Friday evening, none of those requests had been filled.

During the press conference on Friday, sheriff's deputies lined the back wall of the conference room as Sims discussed the incident and his department's response to it.

When asked about why Laghaoui’s family called the police but then decided not to press charges, Sims frowned and shook his head.
